With over 30 years of acoustic beacon design and manufacturing experience for the commercial and military markets, the Dukane Seacom beacons are designed to provide outstanding performance and reliability the aviation and maritime industries require.

Test Sets and Overhaul Kits are also available to verify operation and perform in-field maintenance. Dukane Seacom also offers complete overhaul and repair service for the acoustic beacon products. Please contact us for specific repair/overhaul questions. The DK100/DK130 beacons are sealed units and must be sent back to Dukane for overhaul exchange. The DK120/DK140 beacons, have a field replaceable battery. To determine when your battery is due for replacement, locate the expiration date (the RBB date) on the label.
